5.10 Startup Board PCB5 - (38131)
The startup board assists with the arc creation process. This board provides a current boost during main
arc creation. Arc starting consists of C1and R1 providing increased starting performance. The C1/R1
circuit provides additional current to overcome the inductance of the output inductor at the start of the
main arc.
Testing: Using a capacitance checker to measure, the value of C1, C1 is 56μF capacitor. Using an ohmme-
ter to check the resistance, the value of R1 is equal to 25Ω.
